Ceftriaxone Injection is a broad-spectrum cephalosporin antibiotic that combats bacterial infections by inhibiting cell wall synthesis. After administration, Ceftriaxone Injection binds to penicillin-binding proteins, disrupting peptidoglycan formation, which weakens bacterial cell walls, leading to cell lysis and death. Effective against gram-positive and gram-negative bacteria, ceftriaxone injection treats conditions like pneumonia, meningitis, and urinary tract infections. It is administered intramuscularly or intravenously, achieving high plasma concentrations. Ceftriaxone Injection has a long half-life, allowing once-daily dosing. It is primarily excreted via bile and urine. Side effects may include diarrhea or allergic reactions, but it’s generally well-tolerated.
